If you roll 5 dices and get three of the same dices, is it better to leave one and roll one or roll two dices?
My friend is saying that it is better to leave one and roll another, since that will give you a full house in 1/6 probability.
However, I thought it is better to roll both different dices since that will give 5/36 full house and 1/36 yahtzee.
Am I wrong in thinking that it is always better to roll two dices since yahtzee scores more than full house given that both full house and yahtzee are open?

Three friends agreed to meet at 8 P.M. in on of the Spanish restaurants in town. Unfortunately they forgot to specify the name of the restaurant. If there are 10 Spanish restaurants
(a) find the number of ways they could miss each other
(b) find the number of ways they could meet
(c) find the number of ways at least two of them meet each other.

I got 10 * 3 = 30 ways for (a) for (b), I got 10 ways. how do I do (c)?

We are supposed to use the Inclusion-Exclusion principle to solve: "how many bridge hands contain exactly 3 clubs, or exactly 5 diamonds or exactly 3 aces?" I know you do something like: |3 clubs|+|3aces|+|5dimonds| - |3clubs AND 3 aces| - |3clubs AND 5 diamonds| -...... +|all 3 intersected| But I'm really struggling with find the cases where the aces may or may not be a club/diamond.

I'm sorry for the basic question, but I can't figure this out.
Suppose you want to find how many even, non-repeating 3-digit numbers there are. If you choose the last digit to be non-zero, you have $(8) (8) (5) = 320$ possibilities. If you choose the last digit to be zero, you have $(9) (8) (5) = 360$ possibilities. What should I do?

I have this question,
The number of different words that can be formed using all the letters of the word “MATHEMATICS” are?
I solved using the logic that if there are total 11 places so at all the 11 places all the 11 words can come, which gives me 11 to the power 11which is then divided by $2! * 2! * 2!$ \ due to the words M, T and A appearing 3 times.
But the actual solution is $11! / (2! * 2! * 2!)$ , why did they consider “not repetition” ?

A man has five pairs of socks of which no two pairs are the same color. He randomly selects two socks from the drawer. What is the probability that he gets a matched pair?

Came across this,
$ϕ =$ probability of event
$p (y, ϕ) = ϕ^{y} (1 - ϕ)^{(1 - y)} = E x p (\log (ϕ^{y} (1 - ϕ)^{(1 - y)}))$ and now, somehow $E x p (\log (ϕ^{y} (1 - ϕ)^{(1 - y)})) = E x p [\log (\frac{ϕ}{1 - ϕ}) y + \log (1 - ϕ)]$ . I looked to use the power rule for logs to bring down the $y (1 - y)$ in front, the product rule for logs to get an addition to the equation, and the subtraction rule for logs to get the division part of the expression. Upon simplifying, I don't yield the desired expression

My attempt is shown below:
$\begin{aligned} E x p (\log (ϕ^{y} (1 - ϕ)^{(1 - y)})) & = E x p [(1 - y) \log (ϕ^{y} (1 - ϕ))] \\ = E x p [(1 - y) \log (ϕ^{y}) + \log (1 - ϕ)] \\ = E x p [(1 - y) y \log (ϕ) + \log (1 - ϕ)] \end{aligned}$
So, now I'm not sure if this can arrive at the right answer

High school probability is one of those interesting tasks that young students receive as part of their statistics and probability assignments. You should also find the answers to probability exercises for high school along with the high school probability questions that will help you come up with the most efficient solutions. If you would like to focus on statistical challenges, you should also use high school probability problems as well as it is based on our examples. Be it related to equations or graphs that will talk about probability, follow our examples and things will become clearer!
